PUMP.

SPECIFICATION forming part of Letters Patent No. 252,468, dated January 1*?, 1882.

Application filed August 2, 1881. (No model.;l v

- being had to the accompanying drawing, and

- l thread or by bolts or screws.

to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates tothat class of pumps in which the water is lifted or directly forced,

in contradistinction to the lifting of the water by the force of suction and it consists in certain devices and combinations of devices hereinafter described, and specifically set forth in thewclaims.

Referring to the drawing, which isr a front elevation partly in section, A represents the body of thepump, which is transversely mortsed for the reception of the handle B.

G is the delivery-spout, and communicates with the channel of the body (shown by dotted lines) which leads to the cylinder D, (shown in section, as is a portion ofthe body A,) which cylinder is attached to or connected with the body by simple friction, the latter being rounded and driven snuglyinto the cylinder; or they may, if desired, be connected byascrew- The cylinder is provided with a diaphragm, E, having an aperture, F, surmounted with an ordinary ap or hinge` valve, G.

At the end of the shorter arm of the lever or handle, and passingtherethrough, is an eyebolt, H, and connected therewith is the bent rod l, which passes down theontside of the body of the pump, and is abruptly bent inwardly and upwardly into thev cylinder D. The rod I is' furnished with a piston and valve composed of the following parts: a base-nut, J, base-plate K, packing L, capplate M, a circular iap -valve, N, and an outer nut, O. The rod I is threaded for the reception and retention of the nuts J and 0,4and the packing and base and cap plates are centrally perforated for the passage of the rod therethrough. The packing and plates arealso provided with perforations or passages P, which are covered by the circular flap-valve Y.

At the front and back of the body A of the pump are attached supports Q, (one of which only is sl1own,)'which serve to support from and upon the bottom of the well the body and cylinder, as clearly shown, and the sides, being left open, permit a free passage of the water to the cylinder D and a free space for the operation of the rod I, and servingalsoto keep the cylinder in line with the body by means of grooves formed in the surface thereof.

The operation of the pump Ais as follows: The cylinder being submerged, the water-line being not lower than the line It, the leverat its vlon ger arm is elevated, which depresses the rod I, with its piston and the valve N thereto attached. The water durin g'this movementrising through the passages P, lifts the valve N and occupies the space in the cylinder above said valve and below the diaphragm E. Upon depressing the long arm of the lever B the movements of the rod I and its piston are reversed and the resistance or weight of the water closes the valve N, and as this reversed movement continues the water is lifted and forced through valve G and into the channel of the body A and out of the exit or delivery spout C.

The advantages of this construction are simplicily, durability, and the obviation of the necessity ofair-tight and carefully fitted joints,

, so requisite in suction-pumps,and the location of the essential working parts in a submerged position, thus securing protection from freez ing. l

I am fully aware that liftingpumps are well known, and do not broadly claim such; but

What I do claim, and wish to secure by Letters Patent, is-

1. The combination of the body A, cylinder I), having thediaphragm E and valve G, with the handle B, bent rod l, piston K L M, and

valveN,substantially as shown and described.

2. The combination, with the body A and cylinder D, provided with diaphragm E and P therethrough, substantially as shown and .o valve G, of the supports Q, substantially as described. t l shown and described. In testimony whereof I affix my signature in 3. The bent rod I, adapted to operate on the presence of two witnesses. outside of the pump-body and to enter the cylinder D, and provided with the base-nut J, i GEORGE R" HUNTER' perforated base-plate K, packing L, perforated Witnesses: cap-plate M, valve N,and cap-nut O,said base- GEORGE M. UNDERWOOD, plate, packing, and cap-plate having passages H. F. MiLLs.
